The rule has become highly controversial of the last several years, and, perhaps no surprise, Kristen also has a history of thumbing her nose at Cannes over the mandate.

In 2015, Kristen was a very vocal critic of Cannes after 50 women were denied access to see the screening of “Carol” because they were wearing flats. The incident became known as “heelgate.”

In 2016, Kristen went barefoot through the festival’s lawn. And, for another premiere, she opted for Vans sneakers after she finished the red carpet — that same year, Julia Roberts also went barefoot on the red carpet to protest the heel rule.

“Things have to change immediately. It has become really obvious that if [a man and I] were walking the red carpet together and someone stopped me and said, ‘Excuse me, young lady, you’re not wearing heels. You cannot come in.’ Then [I’m going to say], ‘Neither is my friend. Does he have to wear heels?’ It can work both ways,” Kristen said at the time.

In speaking to The Hollywood Reporter after “heelgate,” she said, “There’s definitely a distinct dress code. People get very upset at you if you don’t wear heels or whatever. I feel like you can’t ask that anymore, but it’s still a given.”

“If you’re not asking guys to wear heels and a dress, then you can’t ask me either,” she said.
